This adjustment takes the results from the High/Low Band ALC Modulator and Low Band Bypass Gain calibrations, performs several calculations, and stores the results in another set of calibration arrays that are used when ramp sweep is active. These values correspond to the average values calculated in the High/Low Band ALC Modulator and Low Band Bypass Gain calibrations in each frequency band. The instrument then uses these average values to set the High/Low Band ALC Modulator and Low Band Bypass Gain calibration arrays while sweeping through these bands. Since these calibration arrays are filled from the results of other calibrations, Ramp Sweep should be re-run every time the High/Low Band ALC Modulator and/or the Low Band Bypass Gain calibrations are run.
Connect a GPIB cable between the controller and the signal generator being calibrated.
While performing this adjustment, follow all instructions on the controller display.
If this adjustment fails, perform the following steps in order:
Check the equipment setup (see above). If the setup is incorrect, make the necessary corrections and rerun the adjustment.
If this adjustment fails with the equipment set up properly, refer to the troubleshooting section of the signal generator's service guide. If you do not have a printed copy of the service guide (Option OBW), one is available either on the CD-ROM that came with your signal generator shipment or on the Keysight Website.
If you cannot correct the problem using the troubleshooting procedures in the Service Guide, obtain service from Keysight Technologies. Refer to Contacting Keysight Technologies.
